applications, such as YouTube™. Some applications downloaded from Google Play™
may also consume more power.
• Close and exit applications that you are not using.
• Lower the screen display brightness level.
• Turn off your device or activate the Airplane mode setting if you are in an area with no
network coverage. Otherwise, your device repeatedly scans for available networks, and
this consumes power.
• Use a Sony original handsfree device to listen to music. Handsfree devices demand less
battery power than your device's own loudspeakers.
• Keep your device in standby mode whenever possible. Standby time refers to the time
during your device is connected to the network and is not being used.
• Disable any live wallpaper.

Estimating the standby time of your device
Standby time refers to the amount of time the battery can last when your device is
connected to the network but is not in active use. STAMINA mode, when activated,
continuously evaluates the remaining standby time, which can vary depending on how
you use your device. STAMINA mode is more effective in lengthening the standby time if
you keep the screen of your device locked. If you rarely lock the screen, you may not see
much improvement in battery performance.
When you use your device for the first time, the estimated standby time may not be accurate
since there is no previous usage history to estimate from.
To view the estimated standby time
1 From your Home screen, tap .
2 Find and tap Settings > Power management.
Using Low battery mode
You can activate the Low battery mode feature when the battery level is low. This
feature helps you to adjust the settings for screen brightness and data traffic so that you
